Ò

In Chinese pinyin, ò is the yángqù tone (阳去, falling tone) of "o".

Ò is used to represent Emilian pronunciation: [ɔː], e.g. òs Emilian pronunciation: [ɔːs] "bone".

In Italian, the grave accent is used over any vowel to indicate word-final stress: Niccolò (equivalent of Nicholas and the forename of Machiavelli).

It can also be used on the nonfinal vowels o and e to indicate that the vowel is stressed and that it is open: còrso, "Corsican", vs. córso, "course"/"run", the past participle of "correre". Ò represents the open-mid back rounded vowel /ɔ/ and È represents the open-mid front unrounded vowel /ɛ/.

Ò is the 28th letter of the Kashubian alphabet and represents /wɛ/.

In Macedonian, о̀ is used to differentiate the word о̀д (English: walk) from the more common од (English: from). Both о̀ and о are pronounced as [o].

Ò can be found in the Norwegian word òg which is an alternative spelling of også, meaning "also". This word is found in both Nynorsk and Bokmål.

Ò is used to represent Romagnol pronunciation: [ɔ], e.g. piò Romagnol pronunciation: [pjɔ] "more".

In the Vietnamese alphabet, ò is the huyền tone (falling tone) of "o".

In Welsh, ò is sometimes used, usually in words borrowed from another language, to mark vowels that are short when a long vowel would normally be expected, e.g., clòs (English: close [of the weather]).
